I Specification of Lettere Patent.

retreated Feb. 26,1907.

Application filed September 1, 1906. Serial No. 332.983.

To (L7/Z whom it vnr'ty concern:

sBeit known that I, EDWIN J. GOULD, a

citizen of the United States, residing at Boulder, in the county of Boulder and State of Colorado, have invented la new and useful Comp ensat-ing Gear, ot which the following is a specification.

This invention relates to compensating gear of the type set forth in my United States application, Serial No. 297,343, tiled January 2, 1906, and allow ed April27, 1906.

The obiects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their emciency in operation and to decrease the expense attending their manufacture.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation, partly in section, ot a compensating gear constructed in accordance with the present invention; and F ig. 2 is a horizontal section.

Like re'l'crencemnmerals indicate corresponding parts in the diiierent- 'figures of the drawings.

'A The reference-numeral l indicates a driving element, which prefere-bijvY is in the nature of a hollow disk-shaped casing, as shown. The driving element 1 is adapted to be rotated from any suitable source of power', (not shown,) so as to transmit its motion to the driven elements hereinafter described. The driving element 1 preferably is formed in each of its sides with a pair of' diainetrically Aopposite radial slots 2, in which are slidably mount-ed' pins'or bolts 3. The driven eleincnts'4 preferablyr are in the nature of oppositely-cxtending shafts having their inner ends arranged in close proximityr to each other. The driven elements 4 in one embodiment of' the Ainvention can be connected with the drive-wheels of a motor-car, so that said wheels will be individually driven from the driving element1 in such manner that they can rotate at di'erent speeds in turning curves. Each of the driven elements 4 inside the driving element or casingl is provided with a rigid eccentric 5, Which is connected,by means of alink 6, with lthe slidable pin 3 at one side ot the diriving element 1. Each of the driven elements 4 is also rovided with a second rigid eccentric 7, vv ich is disposed at a right angle with respect to the eccentric -that is to say, a line drawn throughl the long center-ot the eccentric 5 would be disposed at an angle of ninetyde` grecs with respect to a line drawn through the long center of the eccentric 7. The second eccentric 7 is connected, by means of a link 8, to the slidable pin 3 on the side of the driving element opposite the`pin with which the eccentric is connected. lt will be untormed at its inner end with a large eye 9 to surround the eccentric on the driven element 4 and at its outer end with a small eye 10 to surround the adjacent pin 3.

It is believed that the operation of theimproved compensating gear will be understood from the foregoing description in connection with the drawings. The rotation of the driving clement 1 is imparted through the slidable pins 3 and links 6 and 8 to the eccentrics 5 and 7 and driven elements 4. If for anT reason one of the shafts or driven elements 4 should be retarded in its rotationsuch, for example,as when a'rnotor-car is' rounding a curve-the eccentrics 5 and 7 of the element 4 which is retarded will cause the links 6 and 8 to shift their position, whereby the o posite driven element 4, which is nt retarded, will have its rotation accelerate The improved compensating ear of this invention is strong, simple, dura le, and inexpensive in construction, as well as thoroughly efficient in operation.

What is claimed isl. A compensating gear comprising a plurality of driven elements 'each provided with a pair oi eccentrics 'disposed at right angles derstood that each of the links 6 and 8 isr with respect to each other, and a driving ele f ment having slidable links connectedwith said eccentrics. E

s f 2. A compensating-gear comprising epm-gs! i 3. A compensating gear comprising a plutries and'at their outer ends with said pins.

' posed end to 4. A compensating gear comprising a pair of drlven elements consisting of shafts disend and each havlng a pair of eccentrics disposed at right angles with respect to each other,a drive element consisting of a disk-shapedoasmg *surroundinfT said dnven'elements and eccentrics 4and I e1ng l formed with a plurality of diametrieally opi posite radial slots, pins slidably mounted 1n the slots of said driving element, and oppoi siteiy-extending pairs of links each having an i eye at its inner end to receive one of said eci centrics and an eye at its outer end to engage one of said pins. i In testimony that I claim the foregoing as my own I have hereto afIXed my signature v in the presence of two Witnesses. l' l EDWIN J. GOULD.
